Power Steering (Constant Control): Description

Power steering gear consists of a gear housing containing a gear shaft with sector gear, a power piston with gear teeth broached into the side of the piston which is in constant mesh with the gear shaft sector, and a wormshaft connecting the steering wheel to the power piston through a U-joint type coupling. The wormshaft is geared to the piston through recirculating ball contact. Steering valve, mounted on top of steering gear, directs the flow of fluid through the system. Fluid is supplied to steering gear, by an engine driven constant displacement pump through a pressure hose. Oil is returned to pump reservoir from steering gear through a return hose.
